Taken directly from the T-Mobile Arena website: "Reserved Event Parking provides patrons an opportunity to pre-pay for parking at facilities with close proximity to The Arena. Reserved Event Parking is available at Monte Carlo, New York-New York and the Aria Event Garages on a first-come, first-served basis. A discounted rate is available for patrons who purchase prior to the event date. Prices are subject to change. Patrons cannot purchase Reserved Parking on-site at any of the parking facilities the night of the event."Also, taken from the Las Vegas Weekly: "Between 4 and 11 p.m., access to self-parking garages at New York-New York and Monte Carlo, along with the Aria Events Parking garage just north of the arena, will cost $20 a vehicle. But if you prepay at lasvegas.parkmobile.com, you'll score a $10 discount. (Registered hotel guests still park for free)."
